Lonnie Jefferson of Waterford, Pennsylvania, had been one of the first guys on the dyno, and when Trey Davis had finished his pulls at the end of the showdown, it was so close, that we awarded both guys a win, and declared a tie.

Lonnie's '70 Road Runner has been in the family for 16 years, and is powered by a .030-inch over-bored 440. Ross pistons are mounted to a set of stock rods and a factory Mopar steel crankshaft, and a Comp Cams roller cam works the valves in the Indy Cylinder Head aluminum EZ heads. Up top, is an Indy single-plane intake and 950 Demon carburetor. Behind that, the 727 houses a 3,500-stall Turbo Action converter, ending at a Dana 60.

Jim LaRosa—a self-proclaimed speed addict From Strongsville, Ohio, brought his '97 Viper GTS, with a plan to dominate our Challenge. Built by Big 3 Racing in Hinckley, Ohio, (the same guys that won with a turbo Duster last year), Jim's Viper featured a 503-inch V-10 monster, with a factory crankshaft, ProGram main caps, and ARP studs. The crankshaft was offset ground, and a set of billet, Oliver rods move a custom set of Ross pistons. The brain in the short block is a custom-ground roller cam from Comp Cams.

The Third Gen cylinder heads were ported by Big 3, and get a set of oversized valves and Jesel Rockers. The intake—although stock, is also a Third generation Viper unit. The really big power comes from a pair of Comp Turbo "oil-less" turbos, and uses two custom made air/water intercoolers.

5/15

The car is still a streetable car, with such amenities as air conditioning, and a full-boogie sound system.

Joe not only planned to dominate the showdown, he did so with 915.21 horsepower, which was enough to win our Power Adder class.

War Witch

One of our repeat participants from last year, Darren Tedder returned to join our Outlaw Class, driving Terry Brown's '66 Belvedere. Terry's Belvedere, was a once-built-for-racing Mopar that received a time consuming rebuild. As builder Darren Tedder tells us, "It had been totally dismantled, and it had part of an old roll cage in it that somebody put in God-knows-when. It was basically the hull of a car--just quarters and half an old cage in it. There were no doors, hood, fenders or deck lid."

Now however, a 511-inch Hemi is capable of pushing the "brick" to sub-ten-second ¼-mile passes with ease. Darren built the Hemi around a Mega Block, with a Callies forged stroker crankshaft and Oliver connecting rods. CP pistons help create a 10.0:1 compression ratio, and other parts like an LSM solid roller camshaft, Stage V aluminum heads, Donovan gear drive, MSD Pro Billet distributor, and an Indy Cylinder Head intake topped by an 1150 cfm Dominator. Finish the power producer. Headers measure 2¼-inch tubes and 4-inch collectors) are by tti, and mufflers are by DynoMax.

8/15

The transmission is a 727, and the Dana 60 holds 4.56 gears. When the rollers stopped, The Belvee turned 641 horsepower and 557 lb-ft of torque. That was enough for Darren, I mean Terry, or do I mean Darren, to win the Outlaw Class. Sorry Darren, we gotta give Terry the Winner's jacket.

All Tied Up

Trey Davis, a 20-year-old native of Louisville, Kentucky, knows how to find a deal. Listing his occupation as "maintenance", he definitely has the know how to build any car he wants. What he wanted, was a Viper. What he found was a 2003 model that he found on Craigslist. It was owned by a nice lady, and Trey was able to convince her that he needed to be the next owner.

There are not a lot of modifications to the car, in fact, the tech sheet that Trey filled out, read like a factory-spec manual. What a stock '03 Viper does have, is a 505-inch V-10 that makes 500 horsepower. Behind that is a six-speed row-your-own transmission, and a rear end with 3.07 gears. Since the factory rated the horsepower at 500 at the flywheel, it was time to see what the rear tires produced. When the dyno roller stopped, Trey had become one of the Non Power Adder class winners with 432.16 horsepower.

Haulin' the Mail—as much as you want

Twenty-seven year old Travis Jefferson from Waterford, Pennsylvania, is a tree climber by trade (Most of us have gotten too old to climb trees, but I digress). That's a good thing, as he needs "climb" up into his '08 Ram everyday so he can get to work. He's owned this Flame-red beauty since new, but has added a few upgrades along the way.

The upgrades include a Banks Ram Air intake, A TS performance module, a Snow Meth/water injection kit, and those large by huge (7 inch) Finch stacks. There's also a BD intake manifold and a South Bend triple disc clutch. What more does a diesel truck need? Travis has that covered with 911.69 lb-ft of torque.

14/15

Since Travis made enough torque to win our Diesel class, does anyone in Waterford, need anything—and we do mean anything, moved?
